APPARATUS FOR DRYING YARN.`

SPECIFICATION forming part of Letters SPatent No. 541,922, dated July 2, 1895. Application filed September 27, 1893. Serial No.486,584. (No model.)

To all whom it may concern:

Beit known that I, ORMEROD DUoKwoRTH, a subject of the Queen of Great Britain and Ireland, and a resident of the borough of Norristown, county of Montgomery, State of Pennsylvania, `have invented a certain Improved Apparatus for Drying Yarn, the.; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved apparatus for drying hanks of yarn or thread and it consists essentially of mechanism for keeping the hank orhanks under constant tension during the drying operation in such manner that the gradual lengthening of the bank, due to the decrease in the amount of moisture it contains, will be taken up during its travel through the machine.

Usually in drying hanks of yarn or thread of any description, the tension exerted on the hank is due, for the most part, to the weight of a reel or roller placed at the lower end of the bank but it has been found impracticable to employ a reel or roller of sufticient weight to keep the yarn perfectly straight and prevent snai-1s and kinking which in some classes of yarn is very apt to occur and if not prevented greatly depreciates its value.

In carrying out my invention I propose to employ two reels or rollers on one of which theA hanks are hung and the other having been passed through the hanks is connected 1 at its opposite ends to tension springs carried by the mechanism for traversing the hanks through the machine, the springs being of sufficient length as to take up any inor rollers are secured upon the carrying chain' and Fig` 4 is a perspective view of a modified form of chain link which may be employed in lieu of that shown in Fig. 3.

The various reels or rollers are supported at suitable intervals upon a single set of carrying chains, one at each side of the machine, and the reels or rollers extending transversely across the machine and being attached at their opposite ends to the chains. These chains are traversed within a drying machine of any suitable construction, the machine shown in the drawings being similar to that described in an application. for Letters Patent of the United States filed b v me on May 13,1892, under Serial No. 432,839. In this machine a current of air is drawn by a fan, F, through a chamber, a2, containing air heating coils and is forced down through the yarn passing through side openings, e, into dues, e', and from thence escaping into a chamber, e2, fromv which it is forced by a fan, F', down through the yarn and escaping by side fines into passage, E3, and from thence into a chamber E5, first passing however through a chamber, E", provided with heating pipes and finally escaping through an opening, A2, provided with an eduction fan,F 2. This series of chambers, fans and flues is contained within a main casing, A, open at the front end so that the hanks of yarn may be readily placed upon or removed from the traversing chains.

In suitable bearings on the casing, A, are mounted transverse shafts, B, B', on which are mounted sprocket wheels, h', forming guides and actuating devices for link belts C, located one at each side of the machine. At intervals the links of this belt are provided with projecting lugs, a, a', extending in opposite directions from different links or as shown in Fig. 4 a single link may be provided with both lugs, a, a. The lug, a, is adapted to receive the end of a reel or roller, b, on

which the hank of yarn or thread is hung, the

connecting the reel or roller, c, to the lug, a', is shown more clearly in Fig. 3, the lug,a being provided with an eye bolt,e, to which the ICO tension springis secured and the opposite end 'of the lspring being provided with a loop for the insertion of the end ofthe reel, c, while the tension of the spring may be adjusted by means of a nut, f, upon the threaded end of' I claim, and desire to secure by Letters Pat- 1. In a yarn drying apparatus having a casing and passages for directing currents of air through the yarn, traversing chains and bearings, rollers provided upon lugs projecting from opposite sides of the traversing chains,

and tension regulating.,r mechanism adapted,

to maintain the hanks of yarn .provided on the rollers in a taut condition, substantially as described.

2. In ayarn drying apparatus, the combination of the traversing chains, roller supports carried thereby, yarn carrying rollers adapted to said supports, and spring tension regulating mechanism acting to maintain the respective rollers of each pair at a given distance apart when the banks of yarn are stretched upon the same and to maintain the yarn provided on the rollers in a taut condition as the distance between the outer ends of the supports of the rollers increases or decreases in the travel of the chains through the apparatus, substantially as described.

3. The combination in a yarn drying inachlne of two yarn reels or rolls for carrying hanks or skeins of yarn, chains for traveling said reels or rollers and springs connecting one of such reels or rollers to the chains.

4. In a yarn drying apparatus traverse chains, C, lugs, a', rollers, c, and tension springs, CZ, securing the rollers to the outer end of the lugs,a,substantial-lysis described.

5. An apparatus for drying yarn comprising a single set of yarn traversing chains, reels or rollers secured to lugs projecting from opposite sides of the chain and adapted to carry the hanks of yarn to be dried and a casing having fines and passages for directing a currentor currents of air through the hanks of yarn, substantially as specified.

6. The combination of the casing having ues or passages for directing or inducing air currents, transverse shafts mounted therein, sprocket wheels carried by such shafts, a single set of carrying chains ,adapted to said sprocket wheels, lugs provided upon said carrying chains and projecting from opposite sides thereof and sets of yarn carrying reels or rollers, the oppositereel of each set being attached to the lugs in such manner that the hank of yarn to be dried will extend across the line of travel of the chains and at an angle thereto, substantially as specified.

7. The combination of the casing having tlues or passages for directing or inducing air currents, traversing chains, means for moving the same through said casing, a lug as et, projecting from one side of said chains, a yarn carrying reel adapted to such lug, lugs, as d', projecting from the opposite sides of such chains,- a second reel or roller and tension Springs extending therefrom Vto the lugs, a', substantially as specified.

S. The combination of acasinghaving flues or passages for directing or inducing the air currents, yarn carrying chains and means for moving the same through the casing, lugs, as a, projecting from one side of the chains and adapted to'carry a reel or roller, lugs, a projecting from the opposite sides of the chains, a second reel or roller, adjustable bolts carried by the lugs, a', and tension springs extending froni said bolts to such second reel or roller, substantially as specified.

In witness whereof I have hereunto set my hand this 21st day of September, A. D. 189.5.
